The Wrong Otherworlder [Slow Burn Isekai/LITRPG]

Kendall was never supposed to be summoned. Dragged into another world by mistake, Kendall lands alone in the Demon Realm with no class, no faction, and a disturbing Skill called Devourer. He expects monsters. Instead, he finds soldiers, merchants, laws, families, prejudice, bureaucracy, and an entire civilization of people who just happen to have horns. Now Kendall has to survive, find his missing friend, and figure out where exactly the line between human and demon was supposed to be.
